Reaction turbine | Main Components of a reaction turbine
Reaction turbine In Reaction turbine major portion of the pressure loss takes place in the rotating wheel. Fluid entering the rotor around its entire circumference is in action. So its rotor need to be so large as compared to the impulse turbine of same power. In reaction turbine, water enters the wheel under pressure and flow over vanes. … [Read more...] about Reaction turbine | Main Components of a reaction turbine
